St. Lucie County school officials take each threat seriously

One day after a student at Fort Pierce Westwood High School said another student passed a note telling of a possible shooting on campus, WPBF 25 News has learned of a Facebook discussion referencing the threat of a shooting at two other St. Lucie County schools.

A Fort Pierce police report stated that a teenager reported being involved in a Facebook conversation with more than 30 others, saying that "white people" were going to "shoot up" schools either Thursday or Friday. The schools listed were Fort Pierce Westwood High School, Fort Pierce Central High School and Forest Grove Middle School.

Authorities said the threat isn't credible, but Fort Pierce police have increased their presence at two of the schools as a precaution.

A girl who attends Westwood High School told WPBF she was able to take a picture of a note that said not to come to school Friday because there could be a shooting.

"Our security department has worked with law enforcement all this week on following through on each one of these individually," St. Lucie County school district spokeswoman Janice Karst said.

An Iranian military observation aircraft flew within 50 yards of an armed U.S. Navy helicopter over the Persian Gulf this month, sparking concern that top Iranian commanders might not be in full control of local forces, CNN has learned.
